We introduce the framework of general probabilistic theories (GPTs for short). GPTs are a
class of operational theories that generalize both finite-dimensional classical and quantum …

Recently, table-top experiments involving massive quantum systems have been proposed to
test the interface of quantum theory and gravity. In particular, the crucial point of the debate …

The formalism of generalized probabilistic theories (GPTs) was originally developed as a
way to characterize the landscape of conceivable physical theories. Thus, the GPT …

A reconstruction of quantum theory refers to both a mathematical and a conceptual
paradigm that allows one to derive the usual formulation of quantum theory from a set of …

Microcanonical thermodynamics studies the operations that can be performed on systems
with well-defined energy. So far, this approach has been applied to classical and quantum …

We study the detection of beyond-quantum nonlocal states that can exist in a theoretical
model whose local systems are standard quantum theory in the framework of general …

To date, there has been no experimental evidence that invalidates quantum theory. Yet it
may only be an effective description of the world, in the same way that classical physics is an …

The computational efficiency of quantum mechanics can be characterized in terms of the
qubit circuit model, which is defined by a few simple properties: each computational gate is a …

Bit commitment is a fundamental cryptographic task, in which Alice commits a bit to Bob such
that she cannot later change the value of the bit, while, simultaneously, the bit is hidden from …

To generate genuine random numbers, random number generators based on quantum
theory are essential. However, ensuring that the process used to produce randomness …
